The three best noise cancelling headphones right now are: 1. Sony MDR-1000x 2. Bose QC35(or Bose QC25) 3. Senheiser PXC-550 Apparently, the Sony MDR-1000X has now beaten the Bose on noise cancellation. It has a lot of cool features, such us letting you turn off the noise canceling by touching the right earphone (I believe) and touch controls. In addition, it beats the Bose with amazing sound quality. Caveat: Expensive, if bought new. There is a build/quality issue at the moment -- where the plastic in the earphone is developing cracks. So buyer beware. The Bose QC35 is/was the standard noise cancellation. I personally think this may be the best recommendation since it has been proven to be a quality product, very comfortable to wear. I personally chose the QC25 over the wireless version (to save money) and also because the QC35 battery is non-replaceable, after certain years if it dies, you cannot replace it and you are out of luck. Whereas, the QC25 batteries are AAA that you can get anywhere. It is wired version, but I am happy with it. Caveat: I own the ATH M50X, and let's just say Bose sound quality is a couple of notches below. But, if you don't know any better, you probably won't notice. The Senheiser PXC-550 has also been getting really great reviews and has pretty comparable noise cancellation as Bose (a notch below). Great sound quality. Lots of cool features like the Sony. Caveat: More expensive than Bose if bought new. I don't like that you have to position the headphones a certain way to turn it off. Could be problematic if you are thinking of just putting the headphone in your book bag without putting it in its case
